   > It looks like a bug that we don't implement GetTablesOperation correctly 
in 3.0, as SHOW VIEWS is missing. I'm fine to backport this PR, or we can 
revert the support of GetTablesOperation. @wangyum what do you think?
   
   We do implement GetTablesOperation correctly in 3.0, just that Simba does 
not use it yet - but keeps using the workaround they used before. Once Simba 
fixes it in the drivers to start using the newly implemented 
GetTablesOperation, the issue will be resolved without SHOW VIEWS.
   
   Simba is working on it and their ETA is to release fixed drivers in 
mid-April. But then Tableau and PowerBI need to integrate it and release 
patches - this would add another 4-6 weeks, and then end users have to upgrade, 
which is another delay.
   Even though it will be fixed on the drivers side, I would propose to 
back-port SHOW VIEWS just to avoid the breakage for users that don't update the 
client.
